The Osaka child abandonment case was a case of child abandonment involving two abandoned children in Osaka, Japan. It occurred in late June 2010 when Sanae Shimomura, a 23-year-old Japanese single mother in Osaka, sealed the door of her apartment shut, abandoning 3-year-old daughter Sakurako Hagi and 1-year-old son Kaede Hagi inside. Neighbors heard the children crying over many weeks until it suddenly subsided, but didn't think anything more of this than simply children in a bad childhood phase. Since Shimomura did not come to work for several days, a colleague went to her place and noticed a strange smell beyond the door. When the police entered the apartment, they found the two children dead.[1] Social workers had attempted to stop by the apartment several times over the course of the children's confinement, but never found anyone home. The apartment was in a lively, populated area, but nobody knew that the children were confined.
Shimamura was arrested on 30 July 2010.[1] She was reported to have wanted free time for herself and was quoted as saying that she had grown "tired of feeding and bathing" her two children on her own.[1]
